    ECAT-2094S ~ NEW ~

    4-Axis Stepper Motor Controller/ Driver

           
    		 

    The ECAT-2094S stepper motor controller is a cost-effective, two-phase bipolar stepper driver. The ECAT-2094S simultaneously controls up to four stepper motors. A motor voltage range between 5 and 46V DC and a maximum motor coil current of 1.5A is being supported. For each motor the maximum running coil current, microstep resolution and other motion parameters are software selectable.

    The ECAT-2094S is a standard EtherCAT slave and an EtherCAT master is required to operate the device. The ECAT-2094S supports three operation modes: Free-Run, SM-Synchron and Distributed Clock (DC).

    Two-phase bipolar stepper motors can be directly connected to the ECAT-2094S device. The device is designed to operate the stepper motor in an open loop. Configuration has to be done by the EtherCAT master and the application program. Each stepper motor is being independently controlled by a separated driver IC. The four driver ICs are not synchronized and work independently from each other. The driver automatically controls the torque and position of the motor. An integrated ramp generator automatically calculates the acceleration and deceleration distance. In position mode the controller drives the motor to the target position and in velocity mode accelerates the motor to the target velocity. All motion parameters can be changed on the fly.

    The ECAT-2094s has four integrated incremental encoder interfaces. Four 32 bit high frequency encoder counter counts the input signal of external  incremental  encoders.  The  encoder  can  for example be used for  homing  purposes  and  for consistency checks.

    High resolution of up to 256 microsteps per full step is supported for a ensuring smooth and precise motor operation.

    For each motor two digital input channels are provided. The digital inputs can be set to act as a simple DI, as a left and right hardware limit switch which automatically stops the motor when activated, or a latch trigger for latching the current motor and encoder position.  

    The module must be supplied by three power sources. Two motor supply and a 24Vdc control supply. Two motors share one power supply.
